Jules Verne: Twenty Thousand Leagues Under the Seas

FIRST PART CHAPTER 14: The Black Current (continued)

Ned Land was just pronouncing these last words when we were suddenly plunged into darkness, utter darkness. The ceiling lights went out so quickly, my eyes literally ached, just as if we had experienced the opposite sensation of going from the deepest gloom to the brightest sunlight.

We stood stock-still, not knowing what surprise was waiting for us, whether pleasant or unpleasant. But a sliding sound became audible. You could tell that some panels were shifting over the Nautilus's sides.

"It's the beginning of the end!" Ned Land said.

". . . order Hydromedusa," Conseil muttered.

Suddenly, through two oblong openings, daylight appeared on both sides of the lounge. The liquid masses came into view, brightly lit by the ship's electric outpourings. We were separated from the sea by two panes of glass. Initially I shuddered at the thought that these fragile partitions could break; but strong copper bands secured them, giving them nearly infinite resistance.

The sea was clearly visible for a one-mile radius around the Nautilus. What a sight! What pen could describe it? Who could portray the effects of this light through these translucent sheets of water, the subtlety of its progressive shadings into the ocean's upper and lower strata?

The transparency of salt water has long been recognized. Its clarity is believed to exceed that of spring water. The mineral and organic substances it holds in suspension actually increase its translucency. In certain parts of the Caribbean Sea, you can see the sandy bottom with startling distinctness as deep as 145 meters down, and the penetrating power of the sun's rays seems to give out only at a depth of 300 meters. But in this fluid setting traveled by the Nautilus, our electric glow was being generated in the very heart of the waves. It was no longer illuminated water, it was liquid light.

If we accept the hypotheses of the microbiologist Ehrenberg-- who believes that these underwater depths are lit up by phosphorescent organisms--nature has certainly saved one of her most prodigious sights for residents of the sea, and I could judge for myself from the thousandfold play of the light. On both sides I had windows opening over these unexplored depths. The darkness in the lounge enhanced the brightness outside, and we stared as if this clear glass were the window of an immense aquarium.
